So you're attitude is basically 'meh, it doesn't affect me so....meh'.
Fine, you do you
What you are skipping over though is that these are matters that do affect millions of people, who feel less meh about it all, either because they have direct, damaging, personal experiences, or simply because (and I put myself in this camp) they believe that in order for things like law, education etc to work properly and in a way that is worthy of respect in a democrtatic society, they need to be on a firm basis of proven fact, not on guesswork or fads and fashions or the feelings of a tiny percentage of the population.
There is no factual basis for the concept 'transgender'. Human beings are either male or female - even when they have DSDs, they have male DSDs or female DSDs. It is impossible to 'transition' to being the opposite sex, so transwomen are not women, and transmen are not men, simply because that is biologically impossible.
Turning education, the law, the media, language, medicine etc upside down on the basis that TWAW/TMAM is turning your [one's] back on a basic, provable scientific fact: humans can't change sex.
You aren't bothered SYH? OK, but other people are bothered about things like scientific fact and matters of principle.
TRAs seem to be shifting away from the indefensible claim that TWareW/TMareM, saying instead that transwomen 'present' as women although they remain biologically male, ditto re TMAM.
In which case, it's my turn to say 'meh' - transfolk can present themselves however they want, no problem with that. But in that case there's absolutely no need for the law, education, medicine, the media, pronouns etc to be turned upside down as it has been in the past couple of decades.
No need for GRCs or GRAs or self-ID or mixed sex toilets or anything - present yourself in whatever gender you want to, folks, that's entirely up to you, but since you are not claiming to actually change sex, there's no need to change the small number of organisational and linguistic structures that are based on biological sex.
